Colonoscopy pressure device
US 6672311 B2
Abstract
This device is used for compressing the abdominal wall and colon during colonoscopy so as to facilitate the colonoscopy exam.
A vest including inflatable bladders is wrapped around a patient. The bladders are inflated to apply pressure to the patient's abdomen. Particularly, the bladders may apply pressure to the sigmoid, descending and ascending the colon of the patient to aid in a colonoscopy. The bladders may be selectively inflated, and deflated, in order to apply any desired amount of pressure to aid the doctor performing a colonoscopy examination. The bladders are enclosed between two layers of plastic to form the vest. The vest is inserted into a pillowcase-type slip, which is disposable. The vest is secured about the patient by such conventional connectors as hook and loop fasteners, located at the opposing ends of the vest.

Description
FIELD OF THE INVENTION

A device for compressing the abdominal wall and colon to facilitate a colonoscopy.

BACKGROUND OF THE INVENTION

Examination of the colon is performed for a variety of medical conditions. The colonoscope, inserted into a patient's rectum, contains a fiberoptic imaging device to provide a view of the colon and to assist in making a diagnosis. In addition to an imaging device, the probe may include a device to perform a procedure such as removing growths, such as polyps.

It is often difficult to advance the colonoscope through the entire length of a colon. Portions of the colon may become distended during the insertion of the colonoscope. The imaging device on the end of the probe may remain stationary or move backwards if this condition is encountered. This is a particular problem because portions of the colon, such as the sigmoid colon, are not fixed within the abdominal cavity. To combat this problem, it is common for a nurse or endoscopy assistant to manually compress the abdomen during the colonoscope insertion. External pressure is applied in an effort to support and move the colon. The application of external pressure helps advance the colonoscope by inhibiting the distension of the colon. However, it is common that the assistant not be able to sustain the correct amount of pressure or in the correct area. The inaccuracy and inadequacy of the application of pressure can result in the difficulty in advancing the colonoscope through the entire colon.

U.S. Pat. No. 5,685,321 (Klingenstein) discloses a device and method to facilitate a colonoscopy by externally compressing the colon. The device is a wrap that surrounds a patient's abdomen and has an inflatable bladder to apply force to the patient's abdomen. The inflatable bladder is placed on the wrap so that it covers the lower left-hand quadrant of the patient's abdomen. This placement allows the sigmoid colon to be supported. The bladder may have an additional flap of material stitched to the wrap or may be coupled to the wrap using hook and loop fasteners. The bladder can be repositioned on the belt. The bladder can have a variety of shapes to apply different compressive forces.

U.S. Pat. No. 4,120,297 (Rabischong et al.) discloses an orthopedic corset for correcting deformations or malformations of the spine. The corset has an inflatable bag enclosed in a fabric envelope.

U.S. Pat. No. 5,391,141 (Hamilton) discloses a device for applying pressure to a patient after body surgery. The device is an air bladder placed over the surgical wound. A vest is positioned directly over the air cushion and retains the cushion in place.

SUMMARY OF THE INVENTION

BRIEF DESCRIPTION OF THE DRAWINGS

In the drawings:

FIG. 1 is a view of the device in use on a patient;

FIG. 2 is an exploded view of the device and slip; and

FIG. 3 is a cross-section of the vest about a patient (shown in phantom).

DETAILED DESCRIPTION OF THE INVENTION

The colonoscopy pressure device 10 is a vest that wraps around the patient. The device 10, as used on a patient, is shown in FIG. 1. The two ends 24, 26 of the vest 11 may be connected to each other to secure the vest 11 about the patient by any known means. Once connected, the vest 11 is tight about the patient. The vest 11 may have rectangular, inflatable bladders 12, 13 that may be selectively inflated and deflated. The bladders 12, 13 may be formed by heat welding two layers 42, 44 of the vest 11 to one another. Also, the bladders 12, 13 may be separately formed and attached to the vest 11 by any other means such as by being stitched into pockets (not shown). As the bladders 12, 13 are inflated, pressure is applied to the abdomen of the patient. Each bladder 12, 13 has a meter valve 15 to slowly reduce the pressure. Pressure maintains the position of the colon to facilitate passage of the colonoscope through the colon.

As the bladders 12, 13 are inflated, greater pressure is applied to the abdomen. The doctor can select the amount of pressure applied by varying the amount of inflation. The placement of the bladders 12, 13 insures the pressure is applied to the correct area of the abdomen. When the center of the vest 11 is aligned with the center of the abdomen, the bladders 12, 13 are in the correct position. The bladders 12, 13 may be separated by approximately one and one half inches on either side of the center of the abdomen to approximately four inches from the centerline as a function of the patient's waist. This is true regardless of the height of the person. The size of the bladders 12, 13 is large enough to cover the entire left and right side of the abdominal wall extending from the rib cage to the inguinal area. For a person 5′8″ and above, the bladders 12, 13 may be approximately ten inches in height and approximately four to five inches in width. For an individual between the height of 5′4″ and 5′8″, each bladder may be approximately six inches in height and approximately three to four inches in width. For individuals 5′ to 5′4″ in height, the bladder size may be approximately five inches in height by approximately two inches in width.

As can be seen in FIG. 2, the vest 11 has a left and right end that are attached to one another about the individual. The two ends may be attached to one another in the posterior or anterior midline. The attachment has to be strong enough so that the vest 11 does not pull apart when the bladders 12, 13 are pressurized. Many conventional connectors, such as hook and loop fasteners 24, 26 (VELCROŽ) are sufficient for this function. The device 10 may be placed within a pillowcase-type slip 30 which may be constructed of any well-known material, such as a soft fabric, for the comfort of the patient. Alternatively, the case may be a disposable plastic sheath. The slip may be disposable for sterile purposes.

The structure of the vest 11 is seen by the depiction in FIG. 3. The vest 11 may be formed of any suitable material by two layers of plastic 42 and 44. The two layers 42, 44 of plastic are joined to one another to form the vest and the bladders 12, 13 are enclosed between the two inner layers 42, 44. The bladders 12, 13 can be inflated by any conventional means, such as hand operated pressure bulbs or a foot operated pump (not shown).

Many alternatives of the invention are possible. For instance, the two ends 24, 26 of the vest 11 can be connected by laces (not shown). In this instance, the laces extend to join or lace together the ends 24, 26. As the laces are tightened, the two ends 24, 26 draw closer to one another to secure the vest 11 about the patient. Also, the device 10 may be a Mae West, but instead of pockets with kapok, there are the inflatable bladders.

While the invention has been described with reference to a preferred embodiment, many modifications and variations would be known to one of ordinary skill in the art without departing from the scope of the invention. The description of the preferred embodiment is not intended to be limiting in any way, but the invention is defined by the appended claims.
